/'0 all 'llF/LUI/h it may concern:

Be it known that I, Clh\RLES A. HUNT, a-

citizcn of the lllnited States, residing at Newhurgh, in the county of Orange and ntate of New York, have invented new and useful Improvements in Sash-Fasteners, of which the following is a specification.

This invention relates to sash fasteners; vand it has for its object the provision of a device of this character which when operatively arranged upon the sashes will positively prevent the same from being opened.

\Vith these ando'ther objects in view, the invention consists of certainnovel features at construction, combination and arrangement of parts, as will-be hereinafter described and claimed. v

In the accompanying drawings: Figure 1 is a perspective view of companion upper and lower sashes, showing the fastener apolied thereto; Fig. 2 is'a vertical section in line 22 of l ig. 1, showing the wedge 11 sash locking position; Fig. 3 is a view aimilar to Fig. 2, showing the wedge adiusted to permit the sashes to he slid to pro .letermined positions; Fig. 4 is a view simiar to Fig. 2, showing the initial contact of ;he lower sash with the wedge so as to adust the latter to a required locked position; Fig. 5 is a horizontal section on line 6--6v of Fig. 1; and Fig. 6 is a perspective view of ;he wedge.

Referring more particularly to the draw- ,ng the upper sash U is provided along one )f its side bars with a metallic rack 1, which 5 vertically-disposed and provided along its ,ongitndinal edges with. guide'ways 3 for the reception of the side flanges 4 of a vertically iliding wedge 5. This wedge has it flanges t extended preferably. at right angles from ;he side walls 6, the latter terminating; at heir upper ends below the top -7 of the vedge, while the side walls 6 are extended u an outward direction from the upper edges of the flanges 4, so as to provide eilee- .ive locking points 7. The flanges 4, hrough their trictional contact with the walls of theevertical guideways oi the rack ar,are adapted to securclyhold the wedge I 11 any adjusted position hetween the ends of he rack bar so that it may be maintained at Specification of Letters Patent Apiiuctltaiiitaaa a a yio; line.- seniii in; 7413256.

Y wilt a point as may depend upon the predetermined adjustiuent that inav he desired of the respective sashes.

The lower sash L is provided at its meeting rail R with a recess 9. the wall 10 of which lying parallel with the inclined surface 10' of the wedge. When the upper sash is moved in a downward direction, or the lower sash moved in an upward directlon, the rack bar'of the upper sash is disposed across the recess of the said lower sash so that the wall 10 of the recess will be brought to bear against the inclined surface oi the wedge, whereupon the wedge will he moved laterally so as to cause the effective locking points of the side walls 6 to be presentcd into one of the passages 11 of the rack bar where they will be enqaqed beneath the adjacent connecting bar or tooth 12. From this construction it is seen that the wedge is both longitlulinallv and laterally shiitahle in the guideways o'l the rack bar. it is evident that the wedge niav be placed at any point in the length of the rack llil as may depend upon the adjustment that is desired oi the rcspective sashes. Moving the sashes to closed position causes a relative separation oi the inclined surface oi" the wedge from the inclined wall 10 of the recess 5) so that no manual operation to eii'ect a release of the wedge is necessary. it is also apparent that the lock is rendered operative irrespective of the sash adjusted. In other words, it is said that the wedge will be brought into proper locking position on movement of the lower sash in an upward direction 0 a nmvcmcnt oi the upper sash in a downward direction.

Various changes in the form, proportion and the minor details of construction may he resorted to witl'lont departing from the principle or sacrificing any of the advantages of this invention, as claimed.

Having thus described my invention, what T claim is in a sash Fastening. upper and lower sliding sashes. a rack ha r carried by the upper sash and provided with longillulinal guideways, a wedge slidahlv mounted upon the rack bar and provided with flanges cxtendmg into the guideways. the said. Wedge being exposed beyond the side of the rack and I and disposed at right angles to vthe said positioned to engage the lower sash, and 1 flanges. means on the wedge adapted to be advanced I In testimony whereof I aifix Inys1gnature into e eetiverloekin'g. engagement with the i in; presence of twolwitnesses teeth of the rack bar on engagement of the CHARLES N wedge with the lower sash, said means consisting of a pair of looking teeth extended 1 Witnesses: 1n an upward and outward direction-from JENNIE O.
